flow-tec makes some awesome stuff. I just ordered them. They are 3/4" i.d. which you cannot find anywhere else without some type of reduction on the male side. Thanks for the tip B.T. Lowe... One of the barbed to male fittings is not on the site but they are adding it. If you call, they can get it for you. https://www.flow-rite.com/store/marine2/retail/default.htm

Tye, what is the thing in the last picture in your email photo series? How are the quick connects held to the sak--do you have the quick connects just between hoses that go to the saks or do you put one of the connects right at the sak opening? What are the clamps that hold the hose to the quick connect pieces?

The first piece goes on the tube just after the ball valve. The ball valve can be had at any hardware store. White plastic with a red handle. Just above the red ring you pinch the black side and it open the teeth that lock the two pieces together. The third is the male on the pump. So you have a male on the pump. A male on the tube end from the pump. A female on the sac. Works like a champ and very quick and easy. You can actually put the disconnect anywhere on any hose.
